[Scilab-users] Batch to export a graph to PNG automatically

[CRETE Denis]

Hello,
I tried the code given in example for the function "driver", on a PC with Windows XP and Scilab 5.5.0: the report has a warning message given below.

-->current_driver = driver()
current_driver  =
 Rec

-->driver("Pos")
ans  =
 Rec

-->xinit(TMPDIR+"/foo.ps")
-->plot2d()
-->xend()
Warning !!!
Scilab has found a critical error (Unknown exception)
with "xend" function.
Save your data and restart Scilab.
       !--error 1
Affectation erronée.
Now, I issue the "driver" command twice:

-->current_driver = driver()
current_driver  =
 Rec

-->driver("Pos")
ans  =
 Rec

-->driver("Pos")
ans  =
 Pos

-->xinit(TMPDIR+"/foo.ps")
-->plot2d()
-->xend()

and I get the graph in ps format correctly in TMPDIR. Is this to be correlated to the behaviour that I observed (only with Scilab) when I try to switch between windows with Alt+Tab (I have to repeat the command twice) ? Should we consider this a bug ?
Best regards
Denis

Hello,

What would be the program to write if I want to export a graph to PNG automatically with scilab ?


driver & xinit are probably what you are looking for:
